▎ 摘　　要

NOVELTY - Preparing high-concentration graphene slurry by graphite by mechanical peeling comprises inserting lithium mechanical shearing extrusion produced by the in-situ microreaction into the atomic layer spacing of the graphite powder using graphite powder as raw material, so that the graphite layer spacing increases and the action force decreases, and then the dielectric zirconium bead shears Shear force, dynamic bonding of graphite surface and forming a concentrated graphene slurry with a graphene content of 10-22 wt%, where multiple effects of solvation and polymer adsorption separate the graphite interlayers and ratio of the 1-5 atomic layer graphene sheets to the graphite powder raw material is greater than or equal to70%. USE - The slurry is useful for graphene-based electrode material as the electrode material of the fuel cell or the flow battery (claimed). ADVANTAGE - The slurry has thinness, lightness and corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing for graphene-based electrode material
